Please sign the honor pledge: On my honor as a student, I have neither given nor received information on this exam. Signed, ______________________ All coordinate systems will be assumed right-handed. Display Technology 1) What is interlaced scanning and why do televisions use this technology? 2) What is 3:2 Pulldown used for? 3) Describe the movements and emissions of the electron gun in a CRT when illuminating images on the screen of a non-interlaced raster display device. 4) True or false, there must be tight synchronization between a raster monitors framebuffer, phosphor persistence, and refresh rate? Define these terms and explain. 5) A pixel of a liquid crystal display could be described as a layer of liquid-crystal material sandwiched between two layers of polarizing material. Explain how this pixel is able to control screen illumination. Draw the three layers of the pixel and label the flow of light. 4) True or false, there must be tight synchronization between a raster monitors framebuffer, phosphor persistence, and refresh rate?
